Subject: Use numeric comparison in sort for $displaynum (#2952)
X-Git-Tag: 4.15~85
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=00912add46242f05bb9a1ca032dc3da5ed3919dd;p=i3%2Fi3

Use numeric comparison in sort for $displaynum (#2952)

Eg in the case of sockets:
- X0
- X99
- X100

X99 would be picked instead of X100.
